Michael Lentini was in his Sarasota home when he heard his elevator door open, WFLA reported. While he was expecting a delivery from Amazon, he did not sign up for the Amazon Key service, which allows delivery workers to leave packages inside a home.

“I looked this way because I heard the elevator door open; I thought, ‘Somebody that I know,” Lenitni said.

But it wasn’t a friend. It was the Amazon delivery man walking through his home. The man made it all the way to his master bedroom.

“I instantly froze, because its something that you can’t understand until it happens to you.”
